序言
近段时间不让占座位了，但是手动网上预约太麻烦了，于是写了个程序代替人工预约
正文
经观察预约系统的预约方式为先登录后预约，通过抓包工具获得请求的url的内容。
1. 登录模块
请求的url为：http://xxxxx/api.php/login
请求携带的内容为：账号、密码、验证码，
username: xxxxxxx
password: xxxxx
verify: xxxxx这个好解决，直接上selenium，验证码模块通过验证码识别进行破解输入，直接登录。
2. 预约模块
通过抓包找到请求的url为：http://xxxxx/api.php/spaces/xxxx/book，
请求携带的内容为：
access_token: xxx
userid: xxxx
segment: xxx
type: 1
operateChannel: 2每次请求的url的倒数第二个参数都不同，经过多次预约发现了其规律座位号 = 请求连接数字-4892 ，对于access_token和userid是自动获取的，模拟表单时不必在去获取提交，模拟表单的内容为5个input，access_token和userid的value设置为空，对于segment设置为该间教室的就可(这里就不透露了)，type值设为1，operateChannel的值设为2，表单的action设置为对应的url，然后发送请求即可。
